The 28-year-old brown bear was considered the oldest reproducing female grizzly in the region, attracting throngs of tourists who would camp out each spring as she emerged with cubs she birthed during hibernation, local outlets reported.
“The grizzly bear is an iconic species that helps make the Greater Yellowstone Ecosystem so extraordinary,” said Chip Jenkins, the Grand Teton National Park superintendent.
Grizzly 399 walked with her four cubs along the main highway outside Jackson, Wyoming in 2020.

“Wildlife vehicle collisions and conflict are unfortunate,” Wyoming Game and Fish Department Director Angi Bruce said.
